Finished up the tranny today and was picked up. Here are the rest of the highlights of the build:
The oil return to the case was open up to 3/16" and aligned with the slot in the rear bearing. Then I drilled a 1/8" hole from this passage to the #9 thrust washer.

I modified the valve body to shift as quick and hard as I could without upgrading to a manual body.
First the cutback valve is disabled by reversing the position of the valve and spring. Then the transition and 2-3 backout valves are blocked with steel ball bearings. They required a little filing to allow the cover to fit flush. These keep line pressure up during part throttle and closed throttle conditions.

The spacer plate passages were drilled out to 3/16.

A deep sump filter was installed for the deep pan. Always be sure to reinstall the relief valve and spring under the filter in the order as shown.
